Hazard Toxic by ingestion, inhalation, and skin absorption. TLV: 0.5 ppm; animal carcinogen.
Safety Confirmed carcinogen. Poison by intravenous route. Moderately toxic by ingestion. This material, which so closely resembles aniline in the character of its toxic effects, is actually twice as toxic as aniline. It can cause injury to the blood and the liver. It does not necessarily give any alarm or warning, such as cyanosis, headache, and dizziness, which characterize aniline poisoning. Thus, it may be considered a more insidious poison than aniline, and severe and possibly fatal intoxication may come about through skin absorption. Combustible when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
